Business Savings Accounts in 2026: How to Find the Best Rate, Stay Protected and Handle the Tax

If your business keeps more cash than it needs for next month's bills, a business savings account turns that idle balance into interest. The catch is that the best business savings rates move every week, come with conditions, and are taxed differently depending on whether you're a limited company or a sole trader. This guide is for UK business owners and directors comparing accounts in 2026. It explains the three main types of account, how to judge a rate against the Bank of England's Bank Rate, what the FSCS protects when the depositor is a company, and how the interest is taxed, with worked examples in pounds. We don't name banks or quote live rates, because they change faster than any article; instead you'll get a method to compare them on the day you open. Rules were checked against the Bank of England, FSCS and HMRC in October 2026.

Quick answer

The best business savings rate is the highest AER you can get for the length of time you can genuinely leave the money untouched. Easy-access accounts pay least, notice accounts more, and fixed-term bonds usually most. Use Bank Rate (3.75% in October 2026) as a yardstick, keep each bank's balance within the £120,000 FSCS limit, and remember the interest is taxable.

• Easy access for VAT, payroll and emergencies; notice or fixed term for money you won't need soon

• FSCS covers eligible companies up to £120,000 per banking licence, regardless of size

• Sole traders: business and personal deposits at one bank share a single £120,000 limit

• Companies pay Corporation Tax on interest; sole traders can use the £1,000 / £500 Personal Savings Allowance

• Savings income tax rates rise to 22%, 42% and 47% from 6 April 2027

What a business savings account is (and who can open one)

A business savings account is a deposit account held in the name of a business rather than an individual. It doesn't come with a debit card or direct debits; you move money in and out through a linked business current account. That separation is the point. It keeps reserves, tax money and surplus profit away from day-to-day spending, and it earns interest that a current account usually doesn't pay.

Who can open one depends on the provider. Limited companies and LLPs are accepted almost everywhere. Many banks also open accounts for sole traders, partnerships, charities, clubs and associations, but some business savings products are restricted to incorporated businesses, or to customers who already have a business current account with the same bank. Expect the bank to check the business on Companies House where relevant, verify the identity of directors and people with significant control, and ask what the money is for and where it comes from.

A sole trader can, of course, simply use a personal savings account for tax money. There's no rule requiring a separate business savings account. The trade-offs are that personal and business money get mixed, which makes record-keeping harder, and that the interest is taxed as your personal income either way. Our business bank account guide covers the current account side of this decision.

Types of business savings account: easy access, notice and fixed term

Business savings accounts come in three main shapes. The more notice or commitment you give the bank, the more it will usually pay, because it can rely on your money for longer.

Variants exist. Some easy-access accounts limit the number of free withdrawals a year or drop the rate if you exceed it. Some notice accounts let you withdraw early with a loss of interest. "Tiered" accounts pay a different rate on different balance bands, so the headline rate may only apply above, say, £100,000. Some banks offer "sweep" or "linked" accounts that automatically move surplus over a set balance from the current account. Read the key facts document before you deposit: it states the AER, how interest is calculated and paid, the access terms, and what happens at maturity.

The maturity point is a common trap. Many fixed-term deposits roll into a low-paying account, or a new fixed term at whatever rate applies then, if you don't give instructions. Put the maturity date in your diary with a two-week reminder.

How to judge business savings rates against Bank Rate

The Bank of England's Bank Rate is the anchor for UK savings rates. It's the rate the Bank pays on reserves held by commercial banks, and it feeds into what banks pay depositors and charge borrowers. When it rises, savings rates tend to follow within weeks; when it falls, variable savings rates drop, sometimes quickly. Fixed-term rates are priced on where the market expects Bank Rate to go over the term, so they can move before the Bank actually changes anything.

Bank Rate came down from 5.25% to 5.00% in August 2024, and then in steps to 4.75% (November 2024), 4.50% (February 2025), 4.25% (May 2025), 4.00% (August 2025) and 3.75% (18 December 2025). It has been held at 3.75% at every meeting in 2026 so far, most recently on 17 September 2026. That background explains why business savings rates are noticeably lower than in 2023 and 2024, and why the gap between easy access and fixed terms matters: if you expect rates to keep falling, fixing locks in today's rate; if they rise, a fixed deposit leaves you behind.

As a rough guide, easy-access business accounts often pay below Bank Rate, and accounts paying near or above it usually need notice, a fixed term, a minimum balance or a new-customer arrangement. That's a pattern to sense-check offers against, not a rule. A headline rate well above Bank Rate on easy access deserves a second look at the conditions: introductory bonuses that drop after 12 months, rates that only apply to the first £50,000, or a cap on withdrawals.

How to compare business savings rates properly

Comparison sites rank accounts by headline rate, but the right account depends on how your business uses its cash. Work through these points for each account on your shortlist.

Compare business savings accounts on these points

0/8

• AER, not gross rate — AER shows the annual return including compounding, so it compares monthly and annual interest fairly
• Fixed or variable — and for variable rates, any bonus period and what the rate becomes after it
• Access — instant, notice length, or fixed term; withdrawal limits and penalties
• Balance tiers — which rate applies to your actual balance; minimum and maximum deposits
• Eligibility — limited companies only, or sole traders and partnerships too; need for a current account at the same bank
• Banking licence — FSCS cover is per licence, and several brands can share one
• Interest payment — monthly or annually, and whether it can be paid to your current account
• Opening and funding — online or branch, how long onboarding takes, nominated account rules

FSCS protection for business savings

The Financial Services Compensation Scheme protects deposits if a UK-authorised bank, building society or credit union fails. The limit rose from £85,000 to £120,000 on 1 December 2025, for firms that fail on or after that date. The FSCS says it usually pays within seven days, though complex claims can take longer. Savings accounts, notice accounts and fixed-term deposits are all covered.

Companies are covered whatever their size. Eligibility depends on the depositor's legal form, not its turnover. A limited company or LLP is a separate legal person, so it gets its own £120,000 at each banking licence, separate from its directors' personal savings at the same bank. The main exclusion is most types of regulated financial services firm; eligibility follows the Prudential Regulation Authority's depositor protection rules.

Sole traders share one limit. A sole trader isn't a separate legal entity, so the FSCS adds their business and personal deposits at the same bank together. A plumber with £90,000 in a personal savings account and £50,000 in a business savings account at the same bank has £140,000 on deposit but only £120,000 protected; £20,000 is at risk.

Partnerships get one £120,000 limit for the partnership's account, not one per partner, although each partner keeps separate cover for their personal deposits. Charities are judged on their legal structure: a charitable company or CIO is protected up to £120,000 across its accounts with one banking group.

Brands that share a licence share a limit. One authorised bank can run several brands, and money held across them counts as one deposit for FSCS purposes. Before splitting £200,000 between two accounts to stay inside the limit, check on the FSCS website that the two brands hold separate licences. A company with £200,000 at one bank has £80,000 unprotected; split evenly between two separately licensed banks, all of it is covered.

If a dispute with your bank isn't about failure but service (say, a delayed release of notice funds), complain to the bank first. Micro-enterprises and small businesses with turnover under £6.5 million can usually take unresolved complaints to the Financial Ombudsman Service for free.

How interest on business savings is taxed

Banks pay interest without deducting tax, so the tax is your responsibility. How it's taxed depends on who owns the account.

Limited companies: Corporation Tax on interest

Interest earned by a company is part of its taxable profit. It falls under the loan relationship rules, which broadly tax interest as it accrues in the company's accounts rather than when it's paid, so a 12-month fixed deposit spanning two accounting periods is taxed partly in each. The interest is added to trading profit and the total is taxed at 19% if profits are £50,000 or less, 25% above £250,000, and at an effective rate between those with marginal relief. Inside the marginal relief band each extra pound of profit, including interest, is taxed at 26.5%.

Worked example. A trading company holds a £80,000 reserve in a notice account paying 3.5% AER (an illustrative rate, not a quote). Interest for the year is about £2,800. If the company's other profit is £30,000, total profit of £32,800 sits under the lower limit, so the interest costs £532 in Corporation Tax and the company keeps £2,268. If its other profit is £120,000, the interest falls in the marginal band and costs about £742, leaving £2,058. The same cash left in a current account earning nothing would cost the company the full £2,800 a year in lost return, or around £2,000 after tax.

One trap applies to companies that stop trading. A close company that exists mainly to hold investments, which can include just a bank deposit, is a close investment-holding company and HMRC's manual says it pays the main rate with no small profits rate or marginal relief. A trading company that keeps a cash reserve isn't caught. But a company that has stopped trading and just sits on cash may be, except in the first accounting period after a formal liquidation starts if it wasn't one before. If you're winding down, take advice on timing; see closing a limited company.

Sole traders and partners: personal savings income

For a sole trader or partner, interest on a business savings account is personal savings income, taxed the same way as interest on any personal account. It isn't trading profit, so there's no Class 4 National Insurance on it. Three allowances may cover it. The Personal Savings Allowance lets basic-rate taxpayers earn £1,000 of interest tax-free, higher-rate taxpayers £500, and additional-rate taxpayers £0. The starting rate for savings gives up to £5,000 more at 0% if your other income is below £17,570, reduced £1 for every £1 of other income above the Personal Allowance.

Worked examples. A sole trader with £40,000 profit keeps a £30,000 tax pot in savings at 3.5%, earning £1,050. As a basic-rate taxpayer they get a £1,000 allowance, so £50 is taxable at 20%: £10. A sole trader with £60,000 profit and the same interest is a higher-rate taxpayer with a £500 allowance, so £550 is taxed at 40%: £220. A part-time trader with £15,000 profit has £2,430 of income above the Personal Allowance, leaving £2,570 of the starting rate band plus the £1,000 allowance, so up to £3,570 of interest is tax-free.

Interest is reported on your Self Assessment return. Banks also tell HMRC what they paid you after each tax year, and HMRC may adjust your tax code or send a calculation if you're not in Self Assessment. Joint accounts are split equally unless you tell HMRC otherwise.

What changes from April 2027

The Autumn Budget 2025 announced that tax rates on savings income will rise by two percentage points from 6 April 2027, to 22%, 42% and 47%, across the whole UK. The measure changes the rates, not the Personal Savings Allowance or the £5,000 starting rate band. In the £60,000 example above, tax on the same £550 of taxable interest would go from £220 to £231. This affects individuals, including sole traders and partners. It doesn't change how companies are taxed on interest.

Building a cash plan around your tax deadlines

The best rate means nothing if the money is locked away when HMRC wants paying. Plan accounts around the dates you know are coming. A typical VAT-registered limited company has VAT due 1 calendar month and 7 days after each quarter, PAYE every month, and Corporation Tax 9 months and 1 day after the end of the accounting period. A sole trader has Self Assessment payments on 31 January and 31 July, including payments on account.

A simple three-pot plan for £100,000 of company cash

1. 1

   Easy access — £30,000

   The next VAT quarter, a month of payroll and an emergency buffer. Paid at the lowest rate, but always available.

2. 2

   Notice account — £40,000

   Corporation Tax due in six months. Choose a notice period comfortably shorter than the time left, and diary the date to give notice.

   Tip: Give notice early: the money only arrives after the full period, and weekends don't count in your favour.

3. 3

   Fixed term — £30,000

   Surplus reserves with no planned use for a year. Lock in a 12-month rate and set a reminder two weeks before maturity.

Revisit the split each quarter. As your tax bill grows, move money from the fixed pot to notice as deposits mature. If the plan leaves you with more than £120,000 at one banking licence, add a second bank rather than accept uncovered money. For directors who want the money personally, remember that taking it out of the company means salary or dividends first, taxed as our business tax overview explains.

Opening a business savings account

Most providers let you apply online. For a limited company, have ready the company number, registered office, nature of business and expected deposit; the identity and home address of each director and anyone with significant control; and details of a nominated business current account in the company's name, which is where withdrawals will go. Some banks also want recent accounts or bank statements, especially for larger deposits. Sole traders and partners need personal ID, proof of address and evidence the business trades.

Onboarding can take anything from a few minutes to several weeks, because banks carry out anti-money-laundering checks. If you're chasing a short-lived rate, apply early. Funding is usually by bank transfer from the nominated account, and some accounts must be funded within a set number of days or they close.

Common mistakes with business savings

The first mistake is leaving everything in a current account out of inertia: on a £100,000 balance, even a modest rate is thousands of pounds a year. The second is the opposite, locking tax money in a fixed term that matures after the bill is due. The third is chasing a headline rate without reading the conditions, such as a bonus that falls away after a year. The fourth is breaching the FSCS limit, either by holding too much at one bank or by using two brands that share a licence. The fifth, for sole traders, is forgetting that business and personal savings at the same bank are protected as one. And finally, many directors forget that interest is taxable: a company's interest goes on the CT600, and a sole trader's goes on the tax return.

What to do next

Work out how much cash your business holds beyond the next month's needs, then split it by when you'll need it: tax bills, planned spending and genuine surplus. Compare accounts on the day you're ready to open, using the checklist above, and keep each banking licence under £120,000. Use the compound interest calculator to see what each rate is worth on your balance, and read our business tax overview to estimate the tax bills your savings need to cover.

Frequently asked questions

What is a good business savings rate right now?

Use Bank of England Bank Rate as your yardstick: it was 3.75% in October 2026, unchanged since 18 December 2025. Easy-access business accounts usually pay less than Bank Rate, while notice accounts and fixed-term bonds tend to pay more for locking money away. Compare AER, not gross rate, and check the rate on your balance tier. Rates change daily, so compare on the day you open.

Are business savings protected by the FSCS?

Yes, for eligible depositors. Since 1 December 2025 the FSCS protects up to £120,000 per eligible depositor per banking licence. Companies are generally covered regardless of size, though most regulated financial firms are excluded. A sole trader's business and personal accounts at the same bank share one £120,000 limit, because the law treats them as one person.

Is interest on a business savings account taxable?

Yes. A limited company pays Corporation Tax on interest as part of its profits, at 19% to 25%. A sole trader's interest is personal savings income, so it can be covered by the Personal Savings Allowance (£1,000 for basic-rate taxpayers, £500 for higher-rate) and the £5,000 starting rate for savings. Banks pay interest without deducting tax.

Can a sole trader open a business savings account?

Many banks accept sole traders, partnerships and clubs as well as limited companies, though some business savings accounts are for incorporated businesses only. There's no legal requirement to keep business savings separate as a sole trader, but a separate account makes it easier to ring-fence tax money. The interest is still taxed as your personal savings income.

Should my company use a notice account or a fixed-term bond?

Match the account to when you'll need the cash. Money for VAT and payroll belongs in easy access. A Corporation Tax bill due 9 months and 1 day after the end of the accounting period suits a notice account with a notice period shorter than the time left. Surplus cash you won't touch for a year or more can go in a fixed-term bond, which usually can't be withdrawn early.

Can a limited company open an ISA?

No. ISAs are only for individuals aged 18 or over who are UK resident. A company keeps its cash in business savings accounts and pays Corporation Tax on the interest. A director can pay themselves and then use their own ISA allowance, but that's personal money once withdrawn, taxed as salary or dividends first.
